Center text on an image with Python and OpenCV. Had to come up with it myself as no one was spelling this out anywhere (or google couldn't find it)

I have two Github accounts: oanhnn (personal) and superman (for work).
I want to use both accounts on same computer (without typing password everytime, when doing git push or pull).
Solution
Use ssh keys and define host aliases in ssh config file (each alias for an account).

A pattern for building personal knowledge bases using LLMs.
This is an idea file, it is designed to be copy pasted to your own LLM Agent (e.g. OpenAI Codex, Claude Code, OpenCode / Pi, or etc.). Its goal is to communicate the high level idea, but your agent will build out the specifics in collaboration with you.
The core idea
Most people's experience with LLMs and documents looks like RAG: you upload a collection of files, the LLM retrieves relevant chunks at query time, and generates an answer. This works, but the LLM is rediscovering knowledge from scratch on every question. There's no accumulation. Ask a subtle question that requires synthesizing five documents, and the LLM has to find and piece together the relevant fragments every time. Nothing is built up. NotebookLM, ChatGPT file uploads, and most RAG systems work this way.
macOS comes with a remote desktop application called "Screen Sharing." It is essentially a VNC server and client, and it works really well.
Unfortunately, VNC protocol doesn't include sound, hence neither Screen Sharing for macOS or other VNC clients.
I needed a way to be able to hear various application notifications through Screen Sharing, as well as watch videos or any media hosted by my company. To solve this problem, I came up with a way to support forwarding sound between two Macs.
The idea is to use BlackHole to capture output audio, record it with SoX, and pipe the output to the play command (from SoX) on the remote client. It's not an ideal setup, especially since there's about a second of lag, but it's sufficient if you need to remotely watch videos or hear sound for whatever reason.
